Ball Screw Rolling Spline Compound Unit

Product Description

DKG(J) Ball Screw Rolling Spline Compound Unit

1. ball screw rolling spline compound unit

Ball screw rolling spline composite unit is a new type of composite rolling functional unit developed for the application field of automatic and intelligent production line.The products are widely used in horizontal multi-joint robot (SCARA) Z axis, dispensing machine, welding machine, automatic loader, automatic testing equipment and machining center ATC (automatic tool change) and other rotary motion and linear motion mechanical combination device.Ball screw rolling spline composite unit is a new type of composite rolling functional unit developed for the application field of automatic and intelligent production line.The products are mainly composed of hollow screw spline shaft, ball nut rolling bearing composite unit, spline sleeve rolling bearing composite unit and other parts.

2. Features

● Spline shaft for shaft end structure requirements

The ball screw spiral raceway and rolling spline (straight) raceway are cross-designed on the same shaft, and the ball nut and spline sleeve are respectively integrated with the rolling bearing height. Through the rotation or stop of the ball nut and spline sleeve, the screw spline shaft can be rotated, straight and spiral in 3 forms of compound movement.

● Lightweight, low inertia

Lead screw spline shaft adopts hollow design, the overall weight is light；The ball nut and spline sleeve are integrated with the bearing design, making the radial size of the ball nut rolling bearing compound unit and the spline sleeve rolling bearing compound unit small enough and the moment of inertia extremely low.

● High speed, low noise

Ball screw selection of large lead design, coupled with the rotating unit moment of inertia is very low, low noise at high speed movement.

● Easy to install

The two ends of the ball nut rolling bearing composite unit and spline sleeve rolling bearing composite unit are provided with standard driving pulley connecting parts, which is convenient for user selection and easy installation.

3. the principle of movement

● Basic principle of DKGJ

Output motion diagram	Input (drive pulley)		Output (screw spline shaft movement)
Output motion diagram	Rolling nut end drive pulley nl	Spline sleeve end drive belt nh	Straight line motion up and down (Z) direction	Rotational motion in positive and negative (C) directions
Motion form one:linear motion	Forward set	non-rotation	Downward motion Velocity value=nl×Ph	non-rotation
Motion form one:linear motion	reversal	non-rotation	Upward motion Velocity value=-nl×Ph	non-rotation
Motion form two:rotational motion	Forward set	Forward set 且nh=nl	No exercise	Forward set Revolution value=nh
Motion form two:rotational motion	reversal	reversal 且nh=nl	No exercise	reversal Revolution value=-nh
Movement form three:spiral movement	non-rotation	Forward set	Upward motion Velocity value=nh×Ph	Forward set Revolution value=nh
Movement form three:spiral movement	non-rotation	reversal	Downward motion Velocity value=-nh×Ph	reversal Revolution value=-nh

Note:The Ph in the table is the lead of the ball screw,and the screw rotation is left
